hey @gaurangtandon help me out of this code...!?

```
class Triangle():
def __init__(self, angle1, angle2, angle3):
self.angle1 = angle1
self.angle2 = angle2
self.angle3 = angle3
number_of_sides = 3
def check_angles(self):
if self.angle1+self.angle2+self.angle3 == 180:
return True
else:
return False
my_triangle = Triangle(45, 45, 90)
print my_triangle.number_of_sides
print my_triangle.check_angles()
class Equilateral(Triangle):
angle = 60
def __init__(self):
self.angle1 = self.angle
self.angle2 = self.angle
self.angle3 = self.angle
```
